Something missing from Open Source

Kelly McNeill writes "After going to Source Forge and seeking out an open source GNU CAD project, I found that one existed, but that it had remained dormant for over a year, with no serious effort underway. I cannot function professionally without a CAD graphics program. Neither can any of the world's architects and engineers. So while the computer geek in me revels in open source, it is astounding that it continues to be useless for so many technical people. If I thought that I could take on such a project, believe me, I would certainly try."
